The Public Works Department consists of the divisions of Roads & Drainage, Water and Wastewater.
The Roads and Drainage Division takes care of road, sidewalk, curb and storm drainage maintenance and installation including winter snow removal, rural road grading, municipal drains, ditching, cemetery maintenance and other related activities. There are over 230 km of hard top roads, 53 km of gravel roads, 43 km of sidewalks and 42 culverts and bridges in Minto. There are 118 municipal drains under the Ontario Drainage Act, and over 30 named drains. The TLC section takes care of the flowers and landscaped plantings in downtown streetscapes, community gardens, and other Town facilities in cooperation with local Horticultural Societies.
Each year Public Works also supports the Town’s service contract on over 800 LED street lights within the Town, provides comments on dozens of planning applications and development proposals processed by the Building Department, and responds to thousands of service locates through Ontario One Call.
